LinearPlus is designed to enable planners to create and modify Time Chainage Charts either directly in the LinearPlus System or by importing data from a project that has been set up in a separate Project Management system. The chainage points are the fundamental part of defining physically where an activity takes place thus if the basic project data is held external to LinearPlus then the Chainage data associated with each activity must also be passed to LinearPlus, or added directly in LinearPlus in order for LinearPlus to be able to create the Views.
Time chainage charts are commonly used on linear construction projects such as roads, pipelines and tunnels, time chainage diagrams display activities against both time and distance. The principal benefit is the management of work in confined spaces where typically only one operation can be performed at a time.
PCF originally developed this extension to QEI Exec for TransManche Link, the group set up to construct the Channel Tunnel.
The diagram above (which was created with QEI Exec Time Chainage) shows a chainage diagram for the construction of a section of underground railway. The graphics were imported directly from a CAD system and display the plan and elevation of the line. The centre section is laid out so that the vertical axis displays distances to the same scale, with a horizontal time axis.
Different types of activity are represented by different colours and shading. Activities taking place at the stations (ie not moving along the line) can be seen as horizontal blue blocks, while activities that move along the line (eg boring tunnels, laying track, installing signalling equipment) can be seen as several sets of blocks in diagonal patterns. Final commissioning and test work can be seen as vertical blocks.
In this example, the work starts at one end of the line (top of chart) and moves along to the other. The system is also capable of managing projects where work starts at two or more points simultaneously and displaying the results as a composite chart.
Note also that this is an interactive system, not merely a chart produced by postprocessing project data. Users can for example click on the tasks and move them, with embedded rules managing potential clashes of time and/or space.
LinearPlus is designed to complement existing planning tools where the requirements for chainage chart generation are relatively straightforward. QEI Exec is a complete project management solution which can be extended with a wide range of time chainage functionality to suit an organisation's specific needs. This often means writing bespoke code to interface directly with other corporate systems and databases, or producing complex non-standard diagrams using the CAD graphics capabilities built into the product.
Capabilities of LinearPlus and QEI Exec Time Chainage:
Further to the capabilities of LinearPlus, QEI Exec Time Chainage provides:
LinearPlus requires Windows NT SP3 or later, Windows 2000 or Windows XP or Windows Vista. LinearPlus does not support Windows95/98/ME.
